FAQ/ Error message "Unable to open log file"

When exporting maximum envelopes, the following error message appears:

Unable to open log file

In the menu > Flood Simulation > Export > Export Maximum Envelopes, we specified the following file.

  • BP001 .fsxidx
  • BP002 .fsxidx
  • BP003 .fsxidx


If the log file extension contains a space before it, processing is not possible.

Remove the space before the extension of the log file.

For example, fix it as follows:

  • BP001.fsxidx
  • BP002.fsxidx
  • BP003.fsxidx
